Vanna is a credit layer on Solana. You lend into Vanna’s pools, or open one margin account that holds many collaterals, borrow against it, and use that loan across Solana: spot swaps (Jupiter or Titan), perps (Phoenix), Kamino lending, Perena and delta-neutral vaults, and World.xyz prediction markets. Live app: test.vanna.finance (choose Solana in the chain switcher at the top right).
Vanna runs on a Solana mainnet fork (Surfpool), not public Devnet or Mainnet. Balances are test balances on the fork. If you use Backpack, add the fork RPC https://rpc-devnet.solana.vanna.finance to it (how). Then mint test funds from Deposit → Test funds (Faucet) before any Earn, Margin, Trade, Farm or Predict action.

​
Four steps to start

1

Enter the access code

The test app is private. On your first visit it asks for an access code; enter the one the Vanna team gave you. Your browser remembers it for about 30 days.
2

Sign in

Click Connect wallet at the top right. Sign in with email (a one-time code), Google, X or GitHub, or connect Backpack. See Connect Your Wallet.
3

Backpack only: add the fork RPC

If you use Backpack, add the custom RPC https://rpc-devnet.solana.vanna.finance so it shows fork balances and previews transactions correctly. The purple strip at the top of the app has a Copy button and a Setup guide link. Email and social logins don’t need this.

Mint test funds

Click Deposit in the header, then Mint all under Test funds: 1,000 of each token (10 of each xStock) plus 1,000 CASH for Predict, with no wallet approval. See Faucet.

​
The app at a glance

The header groups the pages the way money flows. On Solana, the app opens on Margin. On the right of the header: the chain switcher (Solana / Stellar), the Deposit button (test funds, receive address and wallet ↔ margin transfers) and your account menu. Outside the app, Vanna MCP lets Claude, Cursor or any MCP-compatible assistant use Vanna for you.

​
Supported assets

Vault receipts you receive from Farm (kSOL, kUSDC, USD*, vbSOL…) stay in your margin account and count as collateral too.
A wallet signature is not the final result. Wait for the confirmation toast and refreshed balances before the next step that depends on it.
